Organic Technologies Inc

Extraction from Aqueous Solutions Critical Fluid Technologies, Inc. has developed a continuous countercurrent extraction process based on a 0.5-oy 10-m column to extract residual organic solvents such as trichloroethylene, methylene chloride, benzene, and chloroform from industrial wastewater streams. Typical solvents include supercritical CO9 and near-critical propane. The economics of these processes are largely driven by the hydrophihcity of the product, which has a large influence on the distribution coefficient. For example, at 16°C, the partition coefficient between liquid CO9 and water is 0.4 for methanol, 1.8 for /i-butanol, and 31 for /i-heptanol.

Enviro-Klean Technologies Inc s (EKTI) KLEAN-MACHINE is a patented ex situ, low-temperature thermal desorption technology used to treat petroleum-contaminated soils. The KLEAN-MACHINE treats soil contaminated with hydrocarbons, volatile organic compounds (VOCs), and petroleum hydrocarbons (with a carbon chain length of 45 carbons or less). The technology also cleans baghouse fines. 

King, Buck Technologies, Inc. s, MultiMode combustion (MMC) system treats volatile organic compound (VOC) emissions from soil vapor extraction (SVE) operations. The sequential operation of a thermal oxidizer (ThermOx) followed by a catalytic oxidizer (CatOx) is the basic concept of the MMC system. The CatOx technology is discussed in a separate technology summary (T0780).
